Is there a way to take a test to see where i fall into the 3-letter code socionics uses? By MBTI i am an infp, and that links me to IEI apparently(Strong Ni), but i also noticed that the Intuition(Ni) and Feeling(Fe) concepts have been reversed. Whereas, in MBTI for an infp it is extroverted Intuition, and introverted Feeling. Am i mistaken or have these concepts reversed.

Also, What are the properties of each of the quadrants? I see that people like to bounce back and forth between 2, and im just curious as to what are the tell-tale signs of each. Essentially, what are the differences between the mindsets?
